A snack cart sells lemonade for $2 and hot dogs for &5. The vendor sold 86 items today for a total of $330. Which equation is true?

Answers

Answer 1

Answer: 2x+5x=330. I'm pretty sure that's it but you didn't list any answer choices.

Answer 2

Answer: I agree as well with both these people if you had listed your options we would have probably a better chance of getting the answer right but I do belive that the equation is right

If B is the midpoint of AC, and AC = 8x-20, find BC.

Answers

Step-by-step explanation:

B is the midpoint of AC, where all 3 points are on the same line.

This means that AB = BC and AB + BC = AC, which is equals to 8x - 20.

Hence, BC = 0.5(8x + 20) = 4x + 10.

What is the probability of not drawing a green marble from a jar containing 7 red, 4 green, 3 white, and 9 blue marbles?

Answers

$7+4+3+9$
$11+12$
$23$

$(23)/(23) - (4)/(23)$

$(23-4)/(23)$

$(19)/(23)$ $chance$

Answer:

Probability of not drawing a green marble is 19/23.

Step-by-step explanation:

A jar is containing 7 red, 3 white, and 9 blue marbles.

Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors

P(G) = 4/(7 + 4 + 3 + 9)

P(G) = 4/23

Now the probability of not drawing a green marble = 1 - probability of drawing a green ball

P = 1 - 4/23 = 19/23

Therefore answer is 19/23.

Find the distance between points M (6,16) and Z (-1,14) to the nearest tenth, please help step by step

Answers

The distance between 2 points P(a, b) and Q(c,d) is given by the formula:

$\displaystyle{d= √((b-d)^2+(a-c)^2)$ ,

Apply the formula for the points M(6, 16) and Z(-1, 14):

$\displaystyle{d= √((16-14)^2+(6-(-1))^2)= √(2^2+7^2)= √(4+49)= √(53)\approx 7.28$

which rounded to the nearest tenth is 7.3 (units)

Answer: 7.3 units

Answer 7.3 Units

use the order of operations

first do

16-14

then 6-(-1)

answers

2^2

7^2

then you will do the ebonites on both of them

giving you

then you add them

4+49

square root 53

square root that and get 7.28

round and get

7.3 units
